Casting a 1 kilogram aluminium wall anchor with the sodacan-furnace, in homemade casting sand by goldsmith SawuGo, heating up one kilogram of aluminium to cast, takes around 1 hour (not including starting the coals..) We have improved the airflow of the furnace by using a big compressor, while a hair dryer doesn’t quite give enough power,

next time we will improve the airflow with a different type of ventilator, while it’s not really good for the compressor to be pumping air for two/three hours in a row. and we will also try a heavier welded casting crucible because the fire extinguisher is quite fragile at high temperatures (especially because we welded two handles on it for saver casting and easier handling
